Dimensional Shifter

has a 2 minute CD like all the other Belt Attachments. (Can only be used while not in combat)

Gives u the [spell=321422] Buff, which makes u invisible for 15 seconds. (u can run directly through enemies like an invisible potion)

The Backfire is [spell=321470], which stops you from using invisibility or stealth abilitys for the next 15 seconds and makes u glow yellow.
(Rogues Vanish works even though it doesn't remove the debuff)

in 14 uses it backfired 2 times

It can be can used in a macro with Potion of the Psychopomp's Speed and combining Invisibility 15 sec's & speed boost of 8 sec's it more effective than using Potion of the Hidden Spirit

I'm finding this ability is really useful in solo PvE. You can move but you can't cast without breaking invisibility. Particularly useful in The Mall, it's great for skipping past mobs you don't want to fight. The failure rate for me has been about 10% and the failure effect is not a big deal. Great little enchant.
